7 Claims.

This invention relates to coin changing equipment of the character adapted for disposition where the public may manipulate the same and where an attendant need not be present to supervise the delivery of the change for coins introduced to the machine.

One of the important aims of this invention is to provide relatively simple, inexpensive and durable mechanism in the nature of a coin changing machine, which mechanism is capable of selectively delivering a predetermined number of coins of a given denomination after one of a number of coins of greater denomination is dropped into the machine to condition the same for manual manipulation.

More specifically, this invention relates to coin changing equipment from which maybe fed a number of coins of a given denomination after the coin to be changed is inserted, the means for feeding coins from the machine being common to all coins inserted thereinto and formed to travel through paths of different lengths, depending upon the denomination of the coin inserted and to be changed.

This invention hasfor a definite obiggt, the provision of coin changing equipment capable of delivering two nickels when a dime is inserted, and live nickels when a quarter is inserted into the machine to render the same operative; such equipment being particularly useful in connection with vending machines for packaged goods where the vending machine is operable only after the insertion of a nickel; it being one of the major problems of the vending machine business to supply proper change at the point of purchase.

The particular manner in which the coins to be changed are disposed in the manually operable mechanism and the precise form of many of the parts of the coin vending ing this invention, constitute minor objects thereof and the same will become apparent during the course of the following specification, referring to the accompanying drawings wherein:

Fig. 1 is a front elevational view of a coin changing machine made in accordance with the present invention and showing the mechanism thereof without a portion of the enclosing case.

Fig. 2 is a horizontal cross sectional view taken on line II--II of Fig. 1.

Fig. 3 is a vertical sectional view taken on line III-III of Fig. .2.

' Fig. 4 is a similar sectional view taken on line IV- -I V of Fig. 2 and looking in the direction of the arrows.

Fig. 5 is a fragmentary through a portion of-the V-V of Fig. 2.

Fig. 6 is a horizontalcrpss sectional ,view through the coin changing machine taken on line VI-Vl of Fig. 1; and

detailed sectional view machine taken on line machine embodyduced into coin Fig. 7 is a perspective stretch-out view illustrating several of the parts employed in the machine for receiving the coin to be changed and delivering the coins constituting said change.

Because the machine embodying the broad concepts of this invention is to be located in a public place, the-mechanism thereof should be securely housed in a sectional case, the base of which should be secured directly to a vertical supporting surface such as the wall of a building.

The cover I2 is hingedly carried by base ill and provided with a key operated latch l4 of conventional design. Cover [2 is provided with coin slots l6 through which either a dime or a quarter l8 and 20 respectively may be introchutes 22 and 24.

An. operating cover I2 extends through a slot 28 therein and into engagement with slide-30; operably mounted between a pair of opposed tracks 32. A bifurcated laterally projecting ear 34 engages pin 36 on habit! of parts to be more fully hereinafter described. The bifurcated end of ear 34 permits moving cover 12 to and from the normal position without employment of special equipment. No part of the cover l2 it attached to the mechanism of the machine, other than through the bifurcated car 34.

All of the parts of the apparatus within the housing, composed of base ill and cover 12, are carried by brackets 40 riveted or otherwise fastened to base l0 and extending forwardly therefrom.

A platform broadly designated by the numeral 42, is horizontally disposed between brackets 40 and includes spaced apart flat sheet metal members 44 and 46.

Member 44 supports a plurality of magazines 48 all arranged vertically and in register with openings formed through said member 44. The particular manner of arranging magazines 48 is important for the coins to be delivered are stored therein. These coins 50 are in this instance, nickels two of which are fed from the machine when a dime is inserted, while five are delivered from the machine when a quarter is inserted.

The letter A designates the two magazines 48 from which nickels 50 are fed when a dime is used, and the letter 13" designates the three magazines 48, the nickels from which are fed in addition to nickels from magazines A when a quarter is used.

Directly beneath member 44 is slidably mounted a feeder plate 52 having openings 54 therethrough in register with magazines 48. Slots 56 and 58 through plate 52 register with similar slots 60 and 82 provided in member 44. These last mentioned slots 60 and 62 receive the coins from conventional slug ejectors 64 and 66, the nature of which need not be detailed for the same are conventional and form no part of this handle 26 slidably carried by rejector when frame I 38 is moved invention. It remains only to be stated that slug ejectors 64 and 86 will divert spurious coins or slugs through chute 68 to stall 10, where the operator may retrieve the same. It is also to this stall 10 that coins 56 are delivered through trough I2 when the machine is properly manipulated. Obviously, an opening in cover I2 allows access to stall I0.

Slide 52 is reciprocably mounted below member 44 and immediately above a cooperating member 14 that has anaperture l6 therethrough and which is cut away as at I8 to-allow freedom of movement in behalf of coin holder 80.

The form of coin holder 80 is important and reference to Fig. 7 will reveal that the same is U-shaped, one leg of which is secured to plate 52 through the medium of screws 82. This normally upper leg 84 of holder 80, in addition to having openings 86 to receive screws 82, is provided with slots 88 and 90. The opposite leg 92 of holder 80 has slots 94 and 96 in opposed relation to slots 90 and 88 respectively. A depending ear 98 cooperates with flange I of leg 84 in maintaining the dime I8 in a vertical position after the same is dropped to a place shown in Fig. 5.

Legs 84 and 92 of holder 80 are spaced apart a suflicient distance to receive frame I 02 that has a stem I04 slidably journalled in slots I06 provided in the side walls of trough 12. Stability is thereby imparted to frame I02 as it is reciprocated through a rectilinear path of travel by manual manipulation of handle 26 by the operator.

Flange I68 depending from leg 84 of holder 80 cooperates with flange I00 in confining frame I02 to a horizontal plane. Angular flange I I0 along one side of frame I02, bears against the edge of leg 92 of holder 80, to assist in returning the holder and plate 52 when all of the parts are brought to a normal position at one end of their path of travel by spring II2, anchored at its one end to member 46 through the medium of ear H4, and while its other end is fastened directly to one end of rack II6. This rack H6 is integral with depending flange H8 at the free side of frame I02. As shown in Fig. 6, rack II6 engages dog I20 as movement in either direction occurs.

After the parts have started through their path of travel, they cannot be reversed until after dog I20 has reached the end of rack I I6. Such expedients are conventional,

Member,46 of platform 42 has an aperture I22 provided therethrough in offset relation with aperture I6 and as will be described later, the coin fed into the machine will drop through aperture I22 into coin box I24 after the parts are moved to deliver certain coins 50 from magazines 48.

A lever I26 slotted as at I28 engages pin I30 for movement about the axis of shaft I32 journalled in bearings I34 and operably joined to yoke I36 to clear slugs or spurious coins from rejectors 64 and 66 by swingingframe I38, as is now wellknown in the art. Thus, if a slug is dropped into either of chutes 22 or 24 and handle 26 forced to that end of its path of travel opposite to its normal position, the slug will be dropped from the by yoke I36. The slug will pass through chute 68 to stall I0.

Means is provided to preclude the introduction of a coin into either of chutes 22 or 24 after one coin has once been dropped thereinto and until handle 26 has been moved to clear the machine. This means is identical for each chute 22 and 24 and is actuated by lever I40 pivoted intermediate 75 its ends as at I42 and moved about said pivotal point when frame I38 has the lower portion thereof swung outwardly, as before mentioned.

A finger I44 pivotally mounted as at I46 on the side of the coin chute 22, for example, has the inturned ends disposed to enter the coin chute through openings I48 and I50. Spring I52 is of the past center character to yieldably hold finger I44 in a position with the inturned ends wherever either the coin or lever lift them. For example, when finger I44 is in the position shown in Fig. l, and a coin is dropped into chute 22, said coin will strike the inner end of finger I44 and move the same about its pivotal point I46 to force the outer end into chute 22 through opening I48. Thus, no coin can be introduced into chute 22 until the coin first mentioned, has passed through the machine and the same cleared by the movement of the manually controllable parts, before described, which results in the pivoting of lever I 40 to a position Where it strikes the inner end of finger I44 to withdraw the outer end of said finger from the place where it restricts chute 22.

Another attachment is secured to slug ejectors 64 and 66 and is clearly shown in Figs. 1 and 2. This attachment insures that the machine will not operate when one of the magazines 48 is empty. Yoke I54 pivoted as at I56 is yieldably held in an inoperative position by spring I58. A laterally extending projection I60 lies in the path of travel of follower I62 that rests upon coins 50 in one of magazines 48 of group A, Fingers I64 on yoke I54 move through openings provided for the purpose into the path of travel of the coins in rejectors 64 and 66 when follower I 62 engages projection I60 to overcome the force of spring I58. The coin to be changed, therefore, can be fed into the machine but it is returned through chute 68 to stall I0 so long as magazine 48 wherein follower I62 is disposed, is empty or without a sufficient number of coins 50 to hold follower I62 out of engagement with projection I60.

Coin selectors such as those shown in U. S. Letters Patent No. 2,094,788, may be employed. If so, fingers I64 move into the chute 64, illustrated in said patent, at a point above abutment M to interrupt normal passage and deflect a coin against member 68 to cause the same to drop by gravity through the discharge apparatus of the patented machine (to the left of abutment N), where chute 68 of the instant machine is entered and from whence the coin passes to stall I0.

When the machine is normally operated and a dime I8 is dropped through chute 22, finger I44 will be actuated as above mentioned, to preclude the entrance of another dime until the one introduccd is fed into coin box I24. The end of the path of travel of the dime is at platform 42 and the dime rests in a. vertical position between ear 98, flange I00 and within slot 96 of holder 80. With the dime in such position, handle 26 is moved against the force of spring H2 and frame I02 is carried 'to the right, as seen in Fig. 5. to a point where edge I66 of frame I02 strikes dime I8. From this point on to the end of the path of travel of handle 26, feeder plate 52 is being moved to the right. This movement is sufficient only to carry openings 54 beneath magazines 48 in group A thereof, to a place where they register with aperture 16 in cooperating member I4 of platform 42. The two nickels will thereupon drop through trough 72 into change stall I0. The dime will be deposited in coin box I24 through the other aperture I22 of platform 42.

If a quarter 20 is dropped into chute 24, it will travel to the vertical position shown in Fig. and there rest in slots 94 and 90- of holder 80. The position of coin 20 is very close to edge I66 and as soon as handle 26 is forced to the right to move bar 38 in the direction of the arrow, shown in Fig. 1, edge I66 of frame I02 will immediately strike coin 20 and move feeder plate 52 to carry all-of the openings 54 thereof across aperture 16. As these openings so move, the nickels 50 will drop into trough l2 and be made available to the operator in change stall 10.

From the foregoing, it will be clear to one skilled in the art that the coin changing machine embodying the concepts of this invention might be made to present different physical characteristics than those shown in the accompanying drawings. The important relation of parts revolving about the form of frame I02 and its action upon the inserted coins to be changed, is clear and manifestly important. The machine above described is not complicated and embodies conventionahslug rejectors that may be slightly altered or supplemented to meet conditions without prohibitive expense.
